T0 all'whom iamay con-cern Be it known that I, FREDERICK E. WooD- ward,America, and residing at No. 577 St. Joseph street Lachine Province ofuebec, Do-` minion f Canada, have invented certain new and usefulImprovements in Shoe- Fillers, of which the following is a specifition.

The invention toA be hereinafter described relates to shoe fillers.

he main objects of the invention are to providea marketable,`transportable filler economical in` its' production and use and willhave the following qualities; permanent pliability, proofnesls,elasticity, resiliency, softness and workability, strongly adherent toleather whether wet or dry, tenacious, low melting, quickY cooling, non-shifting.

At present there are two classes of fillers on th market-rubber cementfillers, and ground cork fillers. .Neither of these adeuately meets-thedemands.V The first is dangerous from fire and is wasteful and expensivebecause of evaporation, While thel second requires a long time t0 set,involving long and expensive delays in the other stepsof manufacture. Tofully and adequately meet all of the requirements hereinfore enumeratedthe present filler has been invented.

It comprises `the ingredients hereinafter` stated', and mixedsubstantially in the manner and proportions set forth in the followftion. Preferably, what will be hereinafter termed the compound, is firstmade.V This compound, which also performs the function of a binder,isthen mixed with a base of ground or granulated cork, sawdust, leatherdust, orany suitable substance of like nature.

The preparation of the above filler is as follows 240 lbs. of resin isheated to the melting point in'a steam jacket kettle or other While itis in a hot iuid state 240 lbs. petrole-um wax or wax tailings is putin, melted, andmixed. To this hot fluid lbs. of bircarbonate of sodawhich is stirred in until thoroughly hot Huid mass is mixed market asred engine oil. The o il acts on Specification of Letters Patent.Application tiled August 8, 1913. Serial No. 783,795.

the resin to destroy all tendency to .brittlemass cools and the waxgreatly'increases the flexibility of the resulting mixture or compound.This final compound is soft, semi-plastic, flexible, resi lient`velastic, non-brittle,

workable, low melting, quick cooling, and

described is stirred the base material in the proportion of 25 lbs. ofbase to 6 gals. of compound.4 This completes 'the filler. When allowedto coo] it is ready for use. if desired, it may be put covering theoutside of each loaf with a layer of the .base material in well knownmanner, or it may be put up in barrels or boxes. A filler thus preparedis practically non-infiammable.

`The vheated compound and consequently, the filler containing it, givesofi a nonin flammabley gas, thus substantially preventing combustion ofthe filler.

ated, this filler has the additional qualities of noninlammableness and'smoothness and when being molded into.

specificallyY meniip in loaf form Aby above named are common simi larproperpliable, waterproof, stable, tough, tenacious, adhesive, readily.

l Thus, in atldition to the qualities previously enumer tiolned. Many ofthese are well known on the market and would readily occur to any oneSkilled in the art to which this invention relates. Therefore, they need.not be Set forth here. f

Having fully set forth and described my invention, what I claim anddesire to protectby Letters Patent of the United States.
